AUTOMOBILE PLOW.

SPECIFICATION forming part of Letters Patent No. 766,590, dated August 2, 1904. Appiicaioniedaprnze1903, sesam. 154,149. momma T (all wwwt if; may @anew-11..'

Be it known that I, HENRY B. BURDICK, a citizen of the United States, and a resident of Middleton, in the county of Kay and Territory of Oklahoma, have invented a new and Improved Automobile Plow, of which the following' is a full, clear, and exact description.

The purpose of my invention is to construct a simple and economic form of plow in which the motive power is carried upon the frame of the plow and is suitably connected with the bull or drivingl wheel and to provide means readily accessible to the operator for steering the machine, adjusting' it for hillside work, and regulating' the depth to which the plow shall enter the ground.

r1`he invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had tothe accompanying' drawings, forming a part of this specification, in which similar characters of referenceindicate corresponding' parts in all the figures.

Figure 1 is a side elevation of the machine. Fig'. 2 is a plan view of the same. Fig'. Sis a front elevation. Fig'. A is a detail view illustrating' the means for adjusting' the rear lefthand supporting' or land wheel. Fig. 5 is a detail view illustrating the manner in which the forward end of the beam is connected with the frame of the machine. Fig. 6 is a horizontal sectional view on the line 6 6 in Fig. 1 through the bull-wheel of the machine, illustrating' the manner in which it is supported and the adjusting' mechanism for the wheel; and Fig'. 7 is a vertical section on the line 7 7 in Fig. 2 through the forward portion of the frame, showing' the manner in which the forward end of the plow-beam is raised and lowered to regulate the inclination of the plowpoint in entering' the ground.

A represents the frame of the machine, which consists of a main section 10 and a side extension 11. On this side extension an engine B is suitably supported, together with a boiler C or a gasolene-tank or its equivalent. At the rear of the frame A a platform 12 is preferably located, and above the said platform at the rear of the main section 10 of the frame the drivers seat 13 is secured. A pinion 14 is located on the drive-shaft of the engine B, and this pinion 14 meshes with a gear 15, which gear is secured to a driving-shaft 16, suitably mounted upon the main section 10 of the frame A, as is best shown in Fig'. 2. A clutch 17 is mounted to slide upon the shaft 16 and turn therewith, and a spring' 18 is made to exert pressure upon the said clutch 17 in such manner as to bring' the clutch in locking engagement with the h ub of a sprocketwheel or pulley 19, loosely mounted on the said shaft 16, as is also shown in Fig. 2.

An axle 2O is mounted in the extension 11 of the frame and in the adjoining' portion of the main section 10 of the frame. 2O is located near the rear end of the said frame A and at its outer end is provided with a crank-arm 20, and upon the projection from said crank-arm the left-hand supporting'- wheel or land-wheel 21 is mounted to loosely turn. A lever 22 is loosely mounted on the outer end of the straight portion of the axle 20, as is best shown in Fig'. 4. which lever is provided with a thumb-latch 23, adapted for engagement with a rack 24, secured to the aforesaid extension-section 11 of the frame A, and the said lever 22 is connected byalink 915 with a projection 25 from the crank-arm of the said axle 20, the said projection being adjacent to the hub of the said wheel 21, so that by the operation of the lever 22 the lefthand supporting or land wheel 21 may be raised and lowered to level the machine when employed in hillside work.

A bull or driving' wheel D is loosely mounted upon a shaft 26, which shaft is supported at its left-hand end in a suitable bearing 26 at the left-hand side of the main section 1() of the frame A, as is shown in Figs. Q and 6. This bearing is so constructed that the shaft 26 has vertical movement in the bearing. The opposite end of the shaft Q6 extends in a bearing' 39" in the form of a fixed link, which is at the right-hand side of the main section 10 of the frame A. This bearing is more or less vertically disposed, as is the opposing bearing' 26, and at the forward inner edge of theV said bearing' 39 teeth A0 are produced. A

pinion 39h, which is secured at the right-hand IOO end of the shaft 26, on which the bull-wheel D is loosely mounted, is adapted to engage with the said .teeth40zt for the purposeof rais-l ing and lowering the bull-wheel in order to raise or lower the body of the machine, so that the plow, to be hereinafter described, may be raised a sufficient distance from the ground to pass obstructions when the machine is to be carried from one pointto another or so that the plow may be dropped quickly with the frame to rest upon the ground when the field to be plowed is reached. This adjustment of the bull-wheel is accomplished by securing a worm-wheel ,7 7 on'the shaft 26 and causing the said worm-wheel to be engaged by a worm 78, held to turn in suitable bearings attached to the left-hand side of the main section 10 of the frame A, and this worm 7 8is preferably provided with a polygonal socket, in which a handle v7 9 may be introduced for the purpose of turning the worm and raising and lowering the said bullwheel when required. A large sprocket-wheel 27 is likewise mounted loosely on the shaft 26, and this sprocket-wheel 27, as is shown in Fig. 6, is secured to the bull-wheel D, so that the two turn together. A chain belt 27 a or its equivalent is passed over the sprocket-wheel 27 and over the smaller sprocket-wheel 19 on the driveshaft 16. -The lower stretchof the belt 27 L is engaged byan idler 28, carried by an arm 29, extending downward from theframe at its right-hand side, as is shown best in Fig. 1, and a tension-roller 30 is made to engage with the upper stretch of the chain, which tensionroller 30l is mounted upon a crank-arm 3l, y

heldto turn in a suitable standard 32carried up from the right-hand side of the frame A, and at the outer or right-hand end of the said crank-arm 31 a bar 33 is centrally attached. A spring 34 is secured to the upper end of the said bar and to a rod A 35, which extends forwardly and is secured to the forward righthand portion of rthe frame A, the said rod 35 'being provided with a turnbuckle 36, so'that the spring 34 may be placed under more or less tension. Further, a second spring 37 is secured tothe lower end of the bar 33, and this latter spring extends rearwardly and is attached firmly at its rear end to the rear portion of the frameA at its right-hand side, as is shown in both Figs. 1 and 2.

The clutch-17 is carried out of clutch engagement with the pulley or sprocket-wheel 19 on the drive-shaft 16 through the medium of a lever 38, which is .suitably mounted on a transverse support 38a, located on the main section 10 of the frame, and the rear portion of this lever 38 is made to engage with a transverse rack 39, likewise carried bythe main section 10 of the main frame A. The handle end of theshifting-lever 38 is within convenient reach from thedrivers seat 13.

The forward portion of the frame A is supported by a carriage E, which carriage, asis best shown yin Figs. 3and 7, consists of a cenrtral yoke-section 440, in which a verticallydisposed king-bolt orpiVot-pin 41. is located.

This yoke-section 40 is provided at each side i of its upper portionwith horizontal brackets 42 and at the lower portion of its left-hand side with a larger bracket 43, in which bracket and in the left-hand leg of the yoke 40 an axle 44 is suitably mounted, having a crank-arm 45 at its outer end, and on a spindle carried from the said crank-arm the left-hand forward supporting or land wheel 46 is mounted to turn. This axle 44 may be turned so as raise or lower the said left-hand supportingwheel 46 through the medium of a lever 4 which is securedto the axle 45 and is provided with athumb-latch 48, engaging a rackV the main section lO of the frame Aby an angle bracket or arm 53, as is shown in Fig. 1.

At the rear of this angle arm or bracket 53 a transverse box-frame 54is secured upon the main frame, and preferably a plate 55 is carried from the angle-arm 53 over to the said box-frame 54.

A vertical shaft 56 is mounted to turn in the box-frame, and within the box-frame on the said shaft 56 a drum 57 is secured in any approved manner. At the upper end of the shaft 56 above the box-frame 54 a bevel-gear 58 is attached. A chain 59 is wound around the drum 57, having its ends attached to posts 60, which extend up from the upper brackets 42 at the sides of the yoke-section 40 of the carriage E.

The forward end of a steering-shaft 62 is journaled in a suitable bearing 61, supported by the plate 55, as is shownin Fig. 1, and on this steering-shaft 62 a bevel-pinion 63 is secured, meshing with the teeth of the bevelgear 58, and the said steering-shaft 62 is carried rearward within convenient reach of the drivers seat and terminates at its rear end in a crank-han dle 63, so that by turning the said handle 632L the direction of travel of the machine may be speedily changed as desired.

Y A plow-beam F is located beneath the main This car- TOO IIO

section 10 of the frame A, which beam has Braces 66 are pivoted upon studs 67 at each side of the rear portion of the beam F, and said braces have their forward ends pivoted to the side members of the section 10 of the frame A, as is shown in Figs. 1 and 2 andas is illustrated in Fig'. Vhere the eye 65 connects with the beam F an upwardly-extending' member 65 is located, whereby to adjust the inclination of the point of the plowshare by raising' and lowering' the forward end of the plow-beam F. This adjustment of the forward end of the plow-beam is accomplished, as is shown especially in Figs. l and 7, by connecting' a vertical rod 80 with the said upwardly-extending' member 65, which rod at its opposite end is pivotally attached to onelimb,81,of an elbow-lever 8l,journaled in suitable bearings 82 on the forward upper plate 55 of the main frame, the other limb, 81", of the said elbow-lever 81 being' pivotally connected with a link 83, which is carried to the rear of the machine out of the way of the other mechanism and is att-ached at the rear to a hand-lever 8st, provided with a suitable hand-latch for engagement with a rack 85, the hand-lever Se being' within convenient reach of the operator when occupying' the seat 13. Thus it will be observed that at the will of the operator the point of the plowshare may be raised or lowered `or may be given any inclination the character of the ground may demand.

The plow and its beam may be bodily raised and lowered by the following mechanism: A link 68 is pivoted upon one lug'or stud 67 and upon the crank-arm 69, extending' forwardly and outwardly from a shaft TO, journaled in suitable bearing's Tl, carried by the main section l0 of the main frame A, and this shaft is provided at its outer right-hand end with an upwardly and rearwardly inclined crankarm 72, connected by a link 73 with a lever -i, fulcrumed at the right-hand rear portion of the frame' A within easy reach of the drivers seat. This lifting-lever for the plowbeam has the usual thumb-latch 7 5, adapted for engagement with a rack 76 on the frame A.

It will be understood that in the arrangement of the several parts the bull-wheel D must be so placed that it will keep in the furrow made by the plow.
